CHURN.

SPECIFICATION forming part of Letters Patent No. 584,549, dated June1.5, 1897. Application filed December 26, 1896. Serial No. 617,051. (Nomodel.)l

T0 all whom it may concern:

Be it known that I, MARIEN WALLACE HUTOHINSON, a citizen of the UnitedStates, residing at Adel, in the county of Berrien and State of Georgia,have invented a new and useful Churn, of which the following is aspecification.

My invention relates to churns, and has for its object to simplify andimprove the construction of devices of this class and provide means forsecuring a combined reciprocatory and oscillatory movement of thereceptacle, and to provide simple and efficient means adapted to performthe dual function of guiding the receptacle carrier or holder andsecuring the receptacle in place thereon.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

ln the drawings, Figure l is a perspective view of a churn constructedin accordance with my invention. Fig. 2 is a vertical transverse sectionof the saine.

Similar numerals of reference indicate corresponding parts in bothfigures of the drawings.

The frame of the churn embodying my invention comprises a base 1, havingside uprights 2 and 3, the upright 2 being preferably duplicated to forman intermediate parallelsided space, and a cross-bar 4 connecting theupper ends of the uprights. Suitable braces 5 may be employed to insuresteadiness of the uprights.

Mounted in suitable horizontally alined bearings on the double upright 2is a drivingshaft 6, having an operating crank or handle 7, carrying adriving-wheel S, and operatively connected with this driving-wheel is ahorizontal crank-shaft 9, mounted in alined bearings near the lower endsof the uprights. Any suitable means may be employed for communicatingmotion from the driving-wheel to the crank-shaft, such as a pulley 10 onthe latter, connected by suitable gearing, as a belt 11, with thedriving-wheel.

Arranged for reciprocatory and vibratory movement Within thesupporting-frame is a receptacle carrier or holder 12, mounted at itslower end, which is provided with suitable bearings 13 upon the offsetportion of the crank-shaft 9, and having a platform le, with a centraldepression for the reception of the bottom of the churn-receptacle 15.The carrier or holder is preferably provided with parallel sides 16,forming guides between which the receptacle is seated, and terminallymounted upon these guides for vertical movement independently of thecarrier or holder is a follower 17, adapted to bear upon the top of thechurn-receptacle and hold the latter in its seat on the platform. Themeans illustrated in the drawings for operating this follower consistsof a feed-screw 18, threaded in a countersunlr nut 19 in the upper endof the carrier or holder and swiveled at its lower end in a socket-plate20 in the upper side of the follower. It is my object, however, toarrange this feed-screw to perform the additional function of guidingthe upper end of the receptacle carrier or holder and thus dispense withauxiliary means for this purpose, and hence the feed-screw is arrangedcentrally and vertically of the carrier and is extended through aguide-opening 2l in the cross-bar 4. The upper end of this combinedfeed-screw and guide-rod may be fitted with a crank or handle 22, asillustrated, or with any other equivalent means, whereby rotary motionmaybe imparted thereto to accomplish the adjustment of the followerafter the receptacle has been seated upon the platform.

From the above description it will be seen that in addition to areciprocatory movement the receptacle carrier or holder receives alateral or vibratorymovement by reason of the direct connection ormounting of the lower end of the carrier uponthe offset portion of thecrank-shaft, the upper end of the carrier being, however, guided toreceive only alinear or reciprocatory movement. Thus the lower end ofthe carrier or holder, contiguous to which the receptacle is arranged,is the point of application of motion and has an approximately rotarymovement regulated in throw by the movement of offset of the crankarm.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

IOO

Having described my invention, what I claim s-L p L i. In a churn, theeembination with a supporting-frame, a crank-shaft mounted therein, andmeans for communicating rotary motion to the crank-shaft, of areceptacle carrier or holder guided for linear movement at one end andfulcrumed at the other end upon the oset portion of the crank-shaf t,whereby a combined reciprocatory and oscillatory move; ment is impartedto the carrier, substantially as specified. p 1

2. In a churn, the combination with a sup'- porting-frame, a crank-shaftand means for operating the same, of a receptacle carrier or holdermounted at oney end upon the offset portion of the crank-shaft toreceive' rotary motion therefrom, and a guiderodarraiiged at the otherend of the carrier and -flttediii a guide-opening for reoprooatory andvibratory movement, whereby the carrier receives a combined reciprocatryand vibratory mov el ment, substantially as specified.

3. In a churn, the combination with a 'slip'- porting-frame, acrank-shaft, andfmeans' for communicating rotary motion to theCrankshaft, of a reeeptacle carrier or holder mounted at one end uponthe offset portion of the crank-shaft, a follower mounted upon thecarrier to engage and hold a receptacle seated on the platform of thecarrier, and a feed-sorew connected with the follower to communicatemotion thereto and hold the same at the desired adjustment,saidfeemserew being extended longitudinally through a fixed guide''portion of the vcr'ar'llr-shaft to receive rotary motion therefrom, alfollower mounted on the Carrier, and a feed-screw mounted upon thecarrier and connectedwith the follower whereby the latter may beadjusted to engage and hold a churn-reeepta'cle seated inthe Carrier,the'feed-screw being extended at the opposite end of the carrier fromthe crankshaft through a yguide-opening in Asaid cross-bar in which itlits loosely, whereby the carrieris guided at one end for linearmovement and receives rotary movement at the other end, substantially asspecified. v

In testimonyV that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses. Y y l MARIEN WALLACEHUTGHINSON.
